Hi,

 

I have my PC at home running on Windows 10. I have Virtual box installed on it with some Linux virtual machines running on top.

I would like to access to my PC or even only to my Linux virtual machines when I am at the office using an internet connection.

I would like to do in a way which is secure and I would like to log any unauthorized attempt to gain access to my PC from outside.

My PC at home is connected to the internet using a fritzbox modem/router.

I could also buy a Raspberry to use as a gateway - I have read about it.

 

Could someone help me suggesting a possible approach ? If someone could provide a  guideline with the steps to take then it would be super

 

Thanks in advance :wink:

Massi

What Internet connection do you have at the office? Do you go through a proxy and are you limited to http/https/ftp? Or can you also use ssh?

 

FYI: there are corporations with policies that prohibit you from doing this.

Then configure your VMs to use an IP address on you home network, configure port-forwarding on your modem/router and use ssh.

Maybe your ISP won't allow port 22, so you'll have to use another one. Another reason to choose a higher port is to reduce the amount of brute-force attempts on port 22.
